Summary: The Rancho RS5000X Series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted GMC Sierra 1500HD and Hummer H2 models. Engineered to handle the increased demands of a 4-inch lift, these shocks feature a unique valving system that minimizes harshness during daily driving while maintaining control off-road. The twin-tube construction provides exceptional durability and dent resistance, ensuring consistent performance in rugged environments. Designed as a direct fit for vehicles equipped with Rancho suspension systems, these shocks deliver a smooth, reliable ride for work or play.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a smooth transition between low and high-speed impacts to ensure maximum comfort on various terrains.
• Nitrogen Gas Pressurization: A 150 PSI gas charge provides a quicker response time and reduced aeration to ensure consistent damping performance under load.
• Heavy-Duty Body: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Nitro-Carburized Piston Rod: The hardened 16mm rod provides superior corrosion resistance and seal lubrication to ensure a long service life in harsh conditions.

Frequently Asked Questions

Will these shocks create 4 inches of lift for my truck?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that already have 4 inches of rear lift installed.

What is the benefit of the twin-tube design over a monotube?
The twin-tube design is highly durable; if the outer tube is dented by a rock or debris, the inner cylinder remains functional, allowing the shock to continue operating properly.

Are the dust boots included with this pair of shocks?
Yes, this SKU includes two shocks and comes standard with Rancho’s signature red protective boots to keep the piston rods clear of contaminants.
